16:22 <f_> hello! Has anyone seen this before? > [ 124.444863] mmc0: error -110 whilst initialising SD card

16:23 <f_> This is a 128 GB SanDisk card, trying to get recognised by an S905 KII Pro box.

16:23 <f_> On kernel 6.10.8

16:24 <f_> It's an SD card I'm trying to boot from. U-Boot SPL (my branch), u-boot, and amlogic BL2 recognise it fine, just linux doesn't like it

16:25 <f_> and because the card isn't being recognised postmarketOS cannot fully boot, so the pmOS initramfs goes into a debug shell

16:25 <f_> ~ # ls /dev/mmcblk*

16:25 <f_> ~ # ls /dev/mmcblk*

16:25 <f_> /dev/mmcblk1 /dev/mmcblk1boot0 /dev/mmcblk1boot1 /dev/mmcblk1rpmb

16:26 <f_> ^ and as seen above only the eMMC is recognised

16:31 <narmstrong> I think those are quite problematic, seems minute reported the same

16:32 <narmstrong> Somehow could you provide a ftrace of the mmc transactions ? So I open a ticket with it

16:32 <narmstrong> Does it also fail on uboot ?

16:36 <f_> narmstrong: U-Boot, my branch of U-Boot w/ SPL, and bl2.bin all recognise it fine

16:36 <f_> What's slightly awkward is my other card has the exact opposite symptoms on that S905 board, haha. BootROM doesn't recognise it, but the rest happily boot from it

16:47 <f_> Ok what's even weirder is my gxl board, lepotato, recognises that exact same card just fine...

16:48 <f_> which is weird because IIRC gxbb MMC and gxl MMC are identical...

16:48 <f_> So I'm not excluding the possibility that my S905 board's SD card reader is broken or something similar.

16:50 <lvrp16> Yeah each SoC seem to have different issues. A311D works, S905D3 problematic.

16:53 <f_> love that!

16:54 <f_> but yeah like I said the S905 bootROM did not like the other, different SD card from another manufacturer I have

16:54 <f_> that different card is 2 GB Samsung SD card

16:54 <f_> and once again it works on the lepotato

16:55 <f_> good thing pmOS enters a debug shell so I can have a look at what's going on

19:09 <f_> ok, sorry it took so long:

19:10 <f_> https://bouncy.vitali64.duckdns.org/uploads/funderscore/87c943d7-SD-Fail

19:10 <f_> narmstrong: ^

19:59 <narmstrong> Thx

20:16 <xdarklight> f_: KII Pro inherits meson-gxbb-p20x.dtsi - try removing the sd-uhs-* properties from &sd_emmc_b (those use 1.8V signal voltages which requires an additional voltage regulator on the board - if that's not present switching to UHS modes will fail IIRC)

20:18 <xdarklight> f_: I don't know if u-boot supports or uses the UHS modes. if it stays at the default speed or just uses high-speed (high-speed != UHS) then that may explain why it works in u-boot

21:48 <f_[x]> xdarklight: well that's I think the first SD card that fails to get recognised IIRC

21:48 <f_[x]> But I'll try that
